A γ-ray which has energy of 400 keV collides with an atom andundergoes Compton scattering.
(a) What is the energy of the wave in Joules and hence what isits frequency?
(b) If the change in the angle of the γ-ray is 20°, what is thefrequency of the wave as it exits the atom?
In Aluminium, the attenuation of a γ-ray is described by theattenuation coefficient μ=0.25 cm-1. What are the values for thefollowing:
(c) The relaxation length
(d) The half value thickness
(e)The amount of attenuation of 3 cm of Aluminium, assuming thebuildup factor is 1.
